Below is an image of the floppy disk for the PCX to DXF registered software, complete with a registration key in my name. The author of this program, Phil Koopman Sr., has passed away. As the heir, I am placing this program in the public domain. So, you are free to use this program in any manner you like, but I bear no responsibility whatsoever for maintenance, support, correct functionality, or any damages of any kind whatsoever. Please do not contact me for support -- I don't know where the source code for this is, and have never used it myself.
